Breadth of cuboidal block = 90cm

Height of cuboidal block = 75cm

Volume of cuboid = l×b×h

= 120×90×75

= 8,10,000 cm^3

Side of one cube = 30 cm

Volume of cube =30^3 = 27,000cm^3

No.of cubes = 8,10,000/27,000

Answer 2

Answer:

Volume of cube = l × b × h.

= 120 × 90 × 75.

= 8,10,000 cm^3.

Side of a one cube = 30 cm.

Volume of the cube = 30^3 = 27,000 cm^3.

N.o of cube = 8,10,000/27,000

= 3 .

cubes formed = 3.
